3.4 Parameters: 3-** Reference/Ramps

Parameters for handling of reference, definition of
limitations, and configuration of the reaction of the
frequency converter to changes.

3.4.1 3-0* Reference Limits

3-00 Reference Range

Option: Function:
Select the range of the reference signal and the
feedback signal. Signal values can be positive only,
or positive and negative. The minimum limit may
have a negative value, unless [1] Speed closed loop
control or [3] Process is selected in
parameter 1-00 Configuration Mode.
[0] Min - Select the range of the reference signal and the
Max feedback signal. Signal values can be positive only,
or positive and negative. The minimum limit may
have a negative value, unless [1] Speed closed loop
control or [3] Process is selected in
parameter 1-00 Configuration Mode.
[1] -Max - For both positive and negative values (both
+Max directions, relative to parameter 4-10 Motor Speed
Direction).
